Question

我正在尝试连接到远程HBase服务器。远程服务器在Ubuntu上运行，运行正常，能够使用Hbase客户端（shell）和Java客户端访问它。但是，当我尝试使用相同的Java客户端从Windows机器连接到该服务器时

 org.apache.hadoop.conf.Configuration hadoopConf = HBaseConfiguration.create();
 hadoopConf.set("hbase.zookeeper.quorum", "Paras-Lenovo");

我收到以下错误：

请注意窗口主机文件中的条目很好，我可以从Windows机器远程登录60010和2181端口的hbase / zookeper端口，因此问题不在于连接。问题Hbase client do not able to connect with remote Hbase server与此类似，但这也无法解决问题。

Answer 1

今天我从远程访问客户端访问hbase时遇到了同样的错误，最终解决了问题。只是为了别人的利益而发布变通方法。

我在远程系统中用于hbase java客户端的库与hadoop系统中的库不同。一旦我使用了同一组库，问题就解决了。

Answer 2

禁用具有hbase服务器的机器的ipv6设置。然后每件事都可以。我有同样的问题bofore。

Answer 3

我觉得这个讨论主题很有用http://apache-hbase.679495.n3.nabble.com/Where-is-HBase-failed-servers-list-stored-td4068803.html。

如果你确定IP没有改变，其他一切都在使用hbase shell工作正常，那么master的重启应该会有所帮助（这是我的情况）

Hbase：此服务器位于发生故障的服务器列表中：localhost / 127.0.0.1:38812
